SAND OR OTHER SPRINKLING MACHINE.

Patented May 26, 1908.

Application filed December 19, 1907. Serial No. 407,257.

To all whom it may concern:

. Be it known that I, NAPOLEON Sr. PETER, a citizen of the United States, residing at Fairlield, in the county of Somerset and State of Maine, have invented new and useful Improvements in Sand or Other Sprinkling Machines, of which the following is a specification.

This invention relates to a machine for sprinkling sand on icy sidewalks or for distributing chemical fertilizer or lime in powdered form, and for similar purposes.

The invention has for one of its objects to improve and simplify the construction and operation of apparatus of this character soso as to be comparatively easy and inexpensive to manufacture, thoroughly reliable and eflicient in use, and easy to main ulate.

A further object of the invention 1s the provision of a sprinkling or distributing machine comprising a pair of concentric drums each provi de dwith perforations and relatively adjustable so as to throw the perforations into or out of register for controlling the discharge of sand or other material.

A further object of the invention is the provision of a wheeled vehicle 011 the axle on which the drums are mounted, in combination with means for connecting or disconnecting the drums with one or both traction wheels for rotating the drums by the movement of the vehicle so as to effectively discharge the material upon the sidewalk to be sanded or ground to be fertilized.

With these objects in view and others, as will appear as the description proceeds, the invention comprises the various novel features of construction and arrangement of parts which will be more fully described hereinafter and set forth with particularity in the claims appended hereto.

In the accompanying drawings, which illustrate one of the embodiments of the invention, Figure 1 is a plan view of the ma chine. Fig. 2 is a section taken transversely through the drums. Fig. 3 is a section taken longitudinally through the drums. Fig. 4 is a rear view of the machine. Fig. 5 is a section of line 55, Fig. 4. Fig. 6 is a-perspective view of a modified form of sprinkling machine. Fig. 7 is a section thereof taken transversely through the drums. Fig. 8 is a sectional view showing one of the traction wheels.

Similar reference characters are employed to designate corresponding parts throughout the several views.

Referring to the drawings, 1 designates an axle 011 the ends of which are traction wheels 2 removably secured. Mounted on the axle is an inverted U-shaped cross member 3 to which are secured .the rear ends of the thills 4 which latter are braced one to the other by the cross piece 5 so as to give rigidity. Supported on the member 3 and thills 4 by the irons 6 is a drivers seat 7.

Mounted on the axle 1 is a cylinder or drum 8 which is closed at its ends by heads 9 and provided with peripheral flanges 10 at the ends. The ball bearings 11 are provided to reduce the friction between the drum and axle, and in order to prevent material from entering the bearings, the axle is covered by a tube 12. As shown in Fi 2, the drum 8 has a filling opening 13 through which material is supplied to the drum. On the drum 8 is an outer drum or cylinder 14 which is open at its ends and which is confined between the flanges 10 of the inner drum so that relative longitudinal movement of the drums is prevented, whereby the apertures 15 of the two drums will be maintained in alinement. The apertures of the drums are so distributed that by a relative rotary movement, the apertures can be thrown completely into or out of register or in only partial registration for varying the discharge of material from the drum. The outer drum has an opening 16, Fig. 2, which, when registering with the opening 13, will permit material to be supplied to the inner drum, the opening 16 being normally closed by a hinged cover 17 extending approximately the full length of the drum. In order to readily adjust the drums, the outer drum is provided with grips 18 arranged adjacent the ends and at opposite sides of a cross bar 19 fixed at its ends to the inner drum. Thus by gripping the bar in one hand and one of the grips 18 in the other hand, the drums can be given a relative rotary movement so as to bring the apertures into or out of register.

In order to rotate the drums by means of the traction wheels 2, ratchet and pawl de' vices are employed. Secured to the drum 8 are ratchet wheels 20 disposed between the traction wheels 2 and the ends of the drum,

. and cooperating with each ratchet wheel is 'a pawl 21 mounted on a plate 22 secured to the adjacent traction wheel 2 so that the pawl will, when in engagement with the ratchet wheel, lock the drum with the wheel 2. The pawl can be secured in engaged position in any suitable manner, as for instance, by means of a pin 23 which is inserted in an opening in the plate 22 so as to hold the nose 24 of the pawl in enga ement with the teeth of the ratchet wheel. WVhen it is not desired to rotate the drum, as in transporting the machine from one point to another, the pawl 21 can be held in disengaged position by removing the pin 23 and engaging it over the free arm of the pawl, as shown by dotted lines in Fig. 5. Either one or both of the pawlscan be thrown into locking position at one time when it is desired to distribute the material by the rotation of the drums.

Referring to Figs. 6 to 8 inclusive, the inner drum 24 is provided'with the end flanges 25 between which is arranged the outer drum 26. sections 27 and 28, each of semi-cylindrical form, and the sections are hingedly-connected at 29 so that the outer drum. can be readily taken off for the purpose of cleaning. The section 27 is provided with brackets 30 to which are hingedly connected bolts 31, and on the section 28 are slotted lugs 32 into which the bolts 31 extend, there being wing nuts 33 on the bolts which bear against the lugs to hold the outer drum firmly in place. The outer drum is provided with a door 34 for covering the filling opening, the door being connected with the drum by hinges 35 and held closed by turn buttons 36. Disposed within the inner drum are rods 37 supported on the heads of the drum anddisposed in such a position as to break upthe lumps of frozen sand or other material as the drum rotates. These rods, besides forming pulverizers, serve as stifiening members for the drum.

Rotating with the drum 24 is-a ratchet wheel 38 with which cooperates a springpressed pawl 39 on the traction wheel 40, so that the drum can be rotated with the wheel. If desired, a ratchet wheel and pawl may be employed between the drum and each wheel of the vehicle. When it is necessary to release the drum so that the vehicle can be moved from place to place without the drum turning, a pin 41 is engaged in an opening 42 in the arm 43 of the wheel hub so as to hold the pawl out of engagement with the ratchet wheel. On the outer drum are grips 44 whereby the said drum can be turned between the apertures of the drums into register when it is desired to sprinkle the contents of the inner drum over the ground.

On the ends of the axle 45 are bearings 46 that have diverging lugs 47 and to each bearing is attached a V-shaped frame 48. On the V-shaped frames 48 is mounted a U-shaped This outer drum is composed of two.

{ frame 49 disposed horizontally and arranged the vehicle is comparatively simple and inexpensive and of durable design.

From the foregoing description, taken in.

connection. with the accompanying drawings, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention appertains, and while I have described the principle of operation of the invention, together with the apparatus which I now consider to be the best embodiment thereof, I desire to have it understood that the apparatus shown is merely illustrative, and that such changes may be made when desired as are within the scope of the claims.
